Be Specific When Asking
Gideon said to God, Don't let your anger be kindled against me, and I will speak but this once: Please let me make a trial just this once with the fleece; let it now be dry only on the fleece, and on all the ground let there be dew. God did so that night: for it was dry on the fleece only, and there was dew on all the ground. — Judges 6:39-40
For most assuredly I tell you, whoever may tell this mountain, 'Be taken up and cast into the sea,' and doesn't doubt in his heart, but believes that what he says is happening; he shall have whatever he says. — Mark 11:23

Summary: Faith and prayer must be specific and definite in their requests. We must ask for exactly what we want and expect to receive it. If we do this, God will fulfill our requests exactly as we presented them.
Faith must be definite, specific; enclose within itself an unequivocal and precise request for the things for which we pray. We must have much more than an abstract belief in God's ability and will to work for us. Our requests must be specific and definite, expecting to receive the things for which we ask.
Whenever faith and petition are defined, so will the answer: "whatever I say will be done to you." The guarantee is unlimited, both in quality and quantity.
Faith and prayer select the things to ask for, thereby determining what God is to do. Christ will supply exactly and completely all the demands of the prayer of faith. If we present the request before God in a clear, specific and defined way, God will fulfill it, exactly according to the terms presented.
